APPENDIX. 141 



At p. 19, in the Fauna del Regno di Napoliy M. Costa 

 gives tiie following account of the ne&t o( Nemesia cellicola, 

 which he discovered above Saa Martino in September, 

 1833 :— 



" Vive entro la polvere arida, nelle cavitk oscure delle 

 rauragUe, e propriamente nelle cosi dette Saettiere, ove, col 

 glutine suo, si costrnisce un tubodelicato e mobile, che ha cura 

 di affidare nel suo engine a qualche corpo stabile nel fondo del 

 muro, e che in terra uella polvere, aprendosi I'altro estremo 

 sul piano inclinato dalla polvere stessa costituto." 



This, with the exception of the words " e che in terra nella 

 polvere," which are unintelligible to me as they stand, and 

 appear to want a verb, may be translated as follows: — 



"She lives in the dry dust, in the obscure crevices of walls, 

 and especially in those which are called Saettiere (loop-holed 

 walls?), where she constructs a delicate and flexible tube with 

 her viscid secretion, and which she takes care to fasten at its 

 commencement to some solid body at the bottom of the wall, 



the other extremity opening on the inclined plane 



formed by the dust itself." 



We may remark that there is here no mention of any door 

 or concealment at the mouth of the tube, and in this and 

 some other respects the nest of Nemesia cellicola would 

 appear to resemble the nest oi Aty pus 2:>iceus from the neigh- 

 bourhood of Paris. See above in the text, p. 78. 



B. 



On the Habits of Cteniza Ariana. 



The following is a free translation of an account read by 

 M.Erber before the Botanico Zoological Association of Vienna,* 

 of the very curious observations which he made on Cteniza 

 Ariana when travelling in the Grecian Archipelago. 



" On my return voyage [from Rhodes], I stayed for a fort- 

 night in the island of Tinos, and, among other things, I cap-
